Abstract

Participation in electronic business networks has become necessary for the success of enter¬prises. The strategic business needs for participating in multiple networks simultaneously and for managing changes in these networks are re?ected as new requirements for the supporting computing facilities. The Web-Pilarcos architecture addresses the needs of managed collabo¬ration and interoperability of autonomous business services in an inter-organisational context. The Web-Pilarcos B2B middleware is designed for lowering the cost of collaboration estab¬lishment and to facilitate management and maintenance of electronic business networks. The approach is a federated one: All business services are developed independently and the B2B middleware services are used to ensure that technical, semantic and pragmatic interoperability is maintained in the business network. In the architecture and middleware functionality design, attention has been given to the dynamic aspects and evolution of the network. This article dis¬cusses the concepts provided for application and business network creators and the supporting middleware-level knowledge repositories for interoperability support.
